Specification of Letters Patent.

Application filed June 6, 1910. Serial No. 565,404#

Patented Mar. 26, 1912.

To all whom it may concern:

`Beit known that I, VICTOR M. SUMMA, residing et St.Louis, Missouri and beingr n citizen of thel United States, have invented `certain new and useful Improvements in l lCa.r-l'lnderfrurnes, of 4which the following is Ardrnwinvfs, Wh1ch` illustrate the preferred an full, clear, and'exact description, such as will enable others skilled in the nrt to which it eppertuin's to make and to use the sume,

reference bein had to the lnceoinpanyimg `form ot the invention, though it is to be understood that the invention is not limited to the exact details of construction shown and described, as it is obvious that various modifications thereof will occur, to persons skilledin the art. 1

In seid drawings: Figure 1 is a View partly 1n top plonand partly in horizontal section of e, fragment of o cer underframe embodying. the features of the invention.

Fig. 2 is n transverse, `vertical section taken on the plane indicated by lines 2-2 of Fig. l, and looking in the direction indicated by the, arrow.

Referring to. the drawing by numerals,

: channel draft sills 1 extend from end sill 2 i to built-up bolster 3, through which lutter extends the end of center sill 4.

Obviously the elements illustrated, while only embodying those appearing at one end of e car underfranie, are, ofcourse, dupli cated at the other end thereoig Center sill 4fconsists preferably of e oommerei'ally rolled shape or I section with its web disposed vertienllyfand its flanges outstanding-horizontally, and euch end thereof extends through 'and is framed into the frespective bolster 3." Bolster 3 muy -beof any Well. known builtmpl` type `comprising projecting laterally from the center sill, either ot rolled or pressed shapes common in the art and provided With top and ubottom cover plates, though as' shown for purposes of illustra.-

tion `it comprises e` pair of spaced dit phragms 5 at each sideglof `the center sill extending to the respectiveside sill or side r ,f connectin member 6, cooperating blocks or bolster lil er castin s 7, and top and bottom cover plates 8 en 9. Euch memberif is formed of a Z section though it may be of any desired shape and preferahlyyhes its lower flange lyingr beneath the outer ends of the respective diaphragme 5 and its Web fixed to the end edgeflunge of euch din,- phrngm.

lneh cooperating bloei: 7 is formed of two independent sections each comprising a vertical web 7 and inclined webs 7'b which letter terminate :it their outer edges in flanges 7, The web 7 extends along ond-is riveted tothe web ot the I section forwardly und rearwardly ol' the holster While the forward end 'portions of said web 7 are directed loternlly, that is, otl'set :is at 7" and then extend forward ly parallel with and connected with the web oi'v the draft sills 1, which muy be of any shape with vertical webs.

Fillers or diagonal ribs 7 connect the olfsols 7" with the outer ,portions of Webs 'i' for bracing the ports, and transmitting stresses directly from the draft sills to the center sill. Flonges 7 overlap and nnderlap vthe flanges of the respective drit sill 1 and nre riveted thereto, and said flanges 7c :ire also riveted to the up )er und lower flanges of the respective diopln'agns Fi, the flanges of the draft sills being also riveted to the bolster cover plate. The Webs 7" are inclined, corresponding to and snugly fitting the inner surfaces ol the respective flanges of I section el, so that each section of the said blocks or castings 7 is restricted ortnpered to- 'ward the web of ythe I section, and the inner ends othe respective diephragms are oorrespondinglyrestricted andy extend into the corresponding section oi the member 7, the flanges ol seidy/lli:iphrzigins being riveted to the respective ,vvehs 7, and oooh section of the member Zbeing formed with a. vertical cross web Flying between und riveted to the respective iliarphrnglns i, seid diaphragnis boing spaced to accommodate the Web.

Obviously, the element herein ,referred to :is n copernting block Ior bolster filler enstf` ing is a formed filler, und the outstanding portions of the sections thereof .serve us connectors between the draft sills, the bolster mid, the center sill.

The sections of the copereting block s 7 nre formed with registering vertical recesses 'fin their inner feces, and the lower part of inl g. sills and center sill in sustaining the lead imposed and in resisting boiling shocks.
